Block cipher — In cryptography, a block cipher is a symmetric key cipher operating on fixed length groups of bits, called blocks, with an unvarying transformation. A block cipher encryption algorithm might take (for example) a 128 bit block of plaintext as… … Wikipedia

Block suballocation — is a feature of some computer file systems which allows large blocks or allocation units to be used while making efficient use of slack space at the end of large files, space which would otherwise be lost for other use to internal fragmentation.… … Wikipedia
Block cipher modes of operation — This article is about cryptography. For method of operating , see modus operandi. In cryptography, modes of operation is the procedure of enabling the repeated and secure use of a block cipher under a single key.[1][2] A block cipher by itself… … Wikipedia

Code point — Not to be confused with Point code. In character encoding terminology, a code point or code position is any of the numerical values that make up the code space (or code page).[1] For example, ASCII comprises 128 code points in the range 0hex to… … Wikipedia
Concatenated error correction code — In coding theory, concatenated codes form a class of error correcting codes that are derived by combining an inner code and an outer code. They were conceived in 1966 by Dave Forney as a solution to the problem of finding a code that has both… … Wikipedia
Cyclic code — In coding theory, cyclic codes are linear block error correcting codes that have convenient algebraic structures for efficient error detection and correction. Contents 1 Definition 2 Algebraic structure 3 Examples … Wikipedia
Linear code — In mathematics and information theory, a linear code is an important type of block code used in error correction and detection schemes. Linear codes allow for more efficient encoding and decoding algorithms than other codes (cf. syndrome… … Wikipedia
Repeat-accumulate code — In computer science, repeat accumulate codes (RA codes) are a low complexity class of error correcting codes. They were devised so that their ensemble weight distributions are easy to derive. RA codes were introduced by Divsalar et al. In an RA… … Wikipedia
